The short answer

2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 5 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1994 to 2025.

Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate: Texas’s own results, samples taken from March 11, 2020 to Sept. 9, 2026, with EPA’s 2012 to 2019 file for earlier years.

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the legal limit

65.9ppb

Highest yearly average, 2020 to 2026

2026 average: 11.3 ppb

Averaged by year, the highest was 65.9 ppb, in 2022, below EPA’s legal limit of 80 ppb. Its highest single sample was 117 ppb. In 2026, the latest year on file, its six samples averaged 11.3 ppb. EPA judges this limit at each sampling point, and recorded a violation for total trihalomethanes (TTHM) at this utility in 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 71.5 ppb, in 2015, and EPA recorded a violation in 2016.

46ppb

Highest yearly average, 2020 to 2026

2026 average: 5.3 ppb

Averaged by year, the highest was 46 ppb, in 2023, below EPA’s legal limit of 60 ppb. Its highest single sample was 113 ppb. In 2026, the latest year on file, its six samples averaged 5.3 ppb. EPA judges this limit at each sampling point, and recorded a violation for haloacetic acids (HAA5) at this utility in 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 31.8 ppb, in 2015.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

2.7ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 2.7 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

What handles it

Below EPA’s limits1

Nitrate

Comes from the source

Below EPA’s limits

1.3ppm

Highest sample; found in 33 of 33

2026 average: 0.63 ppm

The highest sample, in 2026, was 1.3 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its three samples averaged 0.63 ppm.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. A & P WSC Pump 1’s own annual report, which it must send you every year, has the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Texas’s results run from March 11, 2020 to Sept. 9, 2026.

Testing your own tap

A & P WSC Pump 1’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Texas certifies.
